SparkFun ToF Range Finder Breakout - VL6180

The SparkFun "Time-of-Flight" (ToF) Range Finder is a versatile and compact breakout for the VL6180 distance sensor. It employs a unique technology that uses a precise clock to measure the time it takes for light to bounce back from a surface, providing more accurate results compared to traditional sensors that depend on reflected light intensity or angles. This technology, which is also employed in cellphones to detect when the phone is held to the ear, makes the ToF Range Finder more immune to noise.

The SparkFun ToF Range Finder is a 3-in-1 module that combines an IR emitter, a range sensor, and an ambient light sensor. The breakout includes all the necessary passives for an easy and cost-effective way to integrate multiple sensors in a project through an I²C interface. All the necessary pins to operate the VL6180 are broken out, including IO1, IO0, SCL, SDA, 2.8V, and GND. However, it is important to note that the ToF Range Finder only accepts 2.8V input and logic, requiring a 2.8V voltage source and level shifting to 3.3V and 5V devices.

Despite the datasheet indicating a maximum absolute range of up to 10cm, the VL6180 has been successfully tested up to 25cm. This extended range further enhances its versatility and usability in various applications.

The ToF Range Finder offers an array of features. It operates on a 2.8V voltage and includes gesture recognition capability. It also comes with two programmable GPIO and two mounting holes for easy installation.

For your convenience, SparkFun provides a variety of resources to help you get the most out of the ToF Range Finder. These include a schematic, Eagle Files, a Hookup Guide, a datasheet for the VL6180, an application note for the VL6180, design files and example code, and a library.

With its unique technology, 3-in-1 functionality, and extended range, the SparkFun ToF Range Finder is an excellent choice for those seeking a reliable and versatile distance sensor solution.
